The Mouse CD5 ELISA Pair Set is for the quantitative determination of Mouse CD5.This ELISA Pair Set contains the basic components required for the development of sandwich ELISAs.The Sino Biological ELISA Pair Set is a solid phase sandwich ELISA (Enzyme-Linked Immunosorbent Assay). It utilizes a monoclonal antibody specific for CD5 coated on a 96-well plate. Standards and samples are added to the wells, and any CD5 present binds to the immobilized antibody. The wells are washed and a horseradish peroxidase conjugated rabbit anti-CD5 polyclonal antibody is then added, producing an antibody-antigen-antibody ``sandwich''. The wells are again washed and TMB substrate solution is loaded, which produces color in proportion to the amount of CD5 present in the sample. To end the enzyme reaction, the stop solution is added and absorbances of the microwell are read at 450 nm.
